How can I change drives using python os?

问题

I'm trying to change the current directory from C: to Y: I tried:

import os
os.chdir('Y:')

but I keep getting an error saying that it can't locate the drive. Essentially I'm looking for the equivalent of the

cd /d

command in cmd.

回答1:

Are you sure Y: really is a valid drive letter?

Try os.chdir('C:') and make sure that works. (It works for me.)

回答2:

If this is a mapped network drive, your best bet is to use the UNC path instead of the mapped path. Also, try to use a raw r string modifier when using paths under windows, if you're not using os.path.join.

import os
print os.getcwd()
os.chdir(r'\\server\path') 
print os.getcwd()
